Restoration
Restoration provides an easy method for copying replicated data from the target back to
its original location on the source. The process only requires you to select the source,
target, and the appropriate replication set. There is no need to select files or to remember
where the data came from on the source since that information is maintained by Storage
Mirroring Recover.
Restoration can be used if the source data is lost due to a disk crash or when the most
up-to-date data exists on the target due to failover. At the time of a source server failure,
your Storage Mirroring Recover target will contain the same data as your Storage
Mirroring Recover source. If you are using the Storage Mirroring Recover failover
capabilities, users can continue updating data on the target server while the problems on
the source are resolved. Because of the continued updates on the target, when the
source server is ready to come back online, the two servers will no longer contain the
same data. Restoration is the process of copying the up-to-date data from the target back
to the original source or a new source.
When a restoration is complete, the source and target are again synchronized.
Replication continues from the target to the source, keeping the two servers
synchronized, until you disconnect the restoration connection.
